Abstract
An isolated multiple-output power supply with a function of detecting the presence or absence of a load at an output port is disclosed. The power supply includes a first voltage source for providing a first voltage at a first node; a first diode having a cathode coupled to the first output port, and an anode coupled to the first node for receiving the first voltage; a second voltage source for providing a second voltage at a second node; a second diode having a cathode coupled to a second output port, and an anode coupled to the second node for receiving the second voltage; and a bridging circuit having two terminals respectively connected to the first and the second output ports. When the load is not present at the first output port, the bridging circuit pulls up an output voltage at the first output port to reverse bias the first diode.
